The CellG3 assay reagent for the measurement of endo-cellulase (endo-1,4-β-glucanase) contains two components;
1) 4,6-O-benzylidene-2-chloro-4-nitrophenyl-β-D-cellotrioside (BCNPG3) and 2) thermostable β-glucosidase. The benzylidene blocking group prevents any hydrolytic action by the β-glucosidase on BCNPG3.  Incubation with an endo-cellulase generates a non-blocked colourimetric oligosaccharide that is rapidly hydrolysed by the ancillary β-glucosidase.  The rate of formation of 2-chloro-4-nitrophenol is therefore directly related to the hydrolysis of BCNPG3 by the endo-cellulase.  The reaction is terminated and the phenolate colour is developed on addition of Tris buffer solution (pH 9.0).

Please note that a new assay kit (K-CellG5) is now available for the measurement of endo-cellulase.  The CellG5 reagent contains a cellopentaose core and exhibits vastly improved sensitivity for some cellulases.  In addition, the exchange of the benzylidene blocking group in CellG3 for 3-keto-butylidene in CellG5 improves the substrate’s water solubility significantly, allowing for a reduction in the concentration of DMSO required in the assay.  As DMSO is known to inhibit certain cellulases, this is another benefit in using CellG5.  Megazyme now recommends the use of K-CellG5 for all assays for the measurement of endo-cellulase.

用于测量内切纤维素酶(内切 1,4-β-葡聚糖酶)的 CellG3 检测试剂包含两种成分;
1) 4,6-O-benzylidene-2-chloro-4-nitrophenyl-β-D-cellotrioside (BCNPG3) 和 2) 热稳定的 β-葡萄糖苷酶。亚苄基封闭基团可防止 β-葡萄糖苷酶对 BCNPG3 的任何水解作用。与内切纤维素酶一起孵育会产生一种非封闭的比色寡糖,该寡糖会被辅助β-葡萄糖苷酶快速水解。因此,2-氯-4-硝基苯酚的形成速度与内切纤维素酶对 BCNPG3 的水解直接相关。反应终止,加入 Tris 缓冲溶液 (pH 9.0) 后酚盐颜色显色。

请注意,现在有一种新的检测试剂盒 (K-CellG5) 可用于测量内切纤维素酶。 CellG5 试剂含有一个纤维五糖核心,对某些纤维素酶的敏感性大大提高。此外,将 CellG3 中的亚苄基封闭基团替换为 CellG5 中的 3-酮亚丁基,显着提高了底物的水溶性,从而降低了检测中所需的 DMSO 浓度。由于已知 DMSO 会抑制某些纤维素酶,因此这是使用 CellG5 的另一个好处。 Megazyme 现在建议在所有测定内切纤维素酶的测定中使用 K-CellG5。
